Ffi th f dbi ts d'a en asea invei 'e'on'wm be asphalt from the followingspecification and the accompanying drawings, wherein a preferredembodiment of the invention has been shown and described.

In the drawings:

Figure 1 is a front view on a vertical plane of a window with a fixedupper sash and movable double hung lower sash, with the weatherstripping indicated by hidden lines.

Figure 2 is a cross-sectional view, in part, of Figure 1 on the line2-2, showing the weather stripping in position on the cross-rails of thelower sash.

Figure 3 is a cross-sectional view, in part, of Figure 1 on the line 33,showing the method of turning the weather stripping about the end of theupper sash rail of the lower sash.

Figure 4 is a cross-sectional view of the weather stripping materialused.

Similar numerals refer to throughout the several views.

As illustrated in the drawings, the fixed upper sash I is formed andconstitutes a part of the main frame 2, with a formed bottom cross-rail3, which has a plurality of Walls and protrusions, including the wall 4.The double hung lower sash 5, movable in a vertical plane, has the siderails 6 and l and the top and bottom cross-rails 8 and 9, respectively.The side rails 6 and 1 have a channel l0, accommodating a U-shapedweather strip H which in turn contacts intimately the sash guide [2,forming a Weather seal between said side rails and the window frame.

The formed bottom cross-rail 9 has an elongated leg I3 which is inturnedat its end forming the groove [4, with a similar groove l5 formed at itsinside base, said grooves l4 and I5 and the similar parts ,2 inside ratea: "said time reef-leg marina the lengt t me ,rbf s'eir 1i metal binderl8 on'thewather's L or inserted, said weather'str ping the ends of saidbottom crass ail strip consists 'of'the' 'pi'l e 'll witlfljtswoye 1?Iii firmly held-in the metal binder F. T H abuts against and tely innerface I821 of [the fa making a weather "seal bet and the bottom'of'the'windo-w frame 2."as-s1'i0w inFigureZ.

A mor'e'uimcu t problem is ing; a, weather seal between 't e an the'upp'ersash I jandthef ofthe loweifsa'sh 5, liarti cularly opening [9between thend'o' and the adjacent wall of'the simple in construction andfree ro which tend to loosen under constant operation of the sash. Iaccomplish this by forming the channel 20 in the wall 2| of thecross-rail 8. said channel extending the entire length of said rail. Inthis channel 20, the metal binder I6 of the weather strip is journaledor inserted, the pile I'I thereof abutting against and intimatelycontacting the adjacent face of the wall 4 of the bottom rail 3 of thefixed upper sash l, making a weather tight seal therebetween. Thechannel 29 in the horizontal rail 8 extends to the out side perimeter ofthe sash 5, regardless of the corner joinery used. The weather stripinserted in said channel 20, is continued and bent in U- shape about theleg 22 of the side rail 1, where it is held in position by the metalbinder [6, the pile I1 thereof abutting against and in intimate contactwith the sash guide [2 and the inner face of the wall 4 of thecross-rail 3, which is extended and warped against and fastened to theframe I, as by the rivet 23, as shown in Figure 3, thereby filling andweather sealing the opening l9 between said cross-rail 8 and the windowframe 2. While I have described in detail above in respect to theweather stripping of one end of the cross-rail 3, it is obvious that thesame methods apply to the opposite end of said rail.

Marked advantage results from the method described above of weatherstripping the sash at the meeting rails and the end opening, in that theweather stripping itself may be easily replaced, if desired, and noadditional parts or members are required, which, due to space limitationand lightness of construction, present many difiiculties during a periodof continued operation.

While I have shown and described herein, for

said binder inserted in said channel extending 7 beyond the ends of saidchannel, the extensions of said weather strip conforming to exteriorsurfaces of the vertical rails.

2.In a window consisting of a formed main frame, upper sash and lowersash, each of said sash having horizontal and vertical rails, saidvertical rails being joined to said horizontal rails at their respectiveends, a formed horizontal upper rail in said lower sash having acontinuous channel therein extending the width of the said sash,adjacent to an abutting horizontal rail of said upper sash, and aweather strip consisting of a metal binder and woven pile fabric firmlyheld in said metal binder inserted in said channel, said weather stripextending beyond the ends of said channel and conforming to exteriorsurfaces of the adjoining vertical rails, where it is held in positionby said metal binder, weather sealing the opening between said sash andthe main frame.

3. A window construction consisting of a formed main frame with a fixedupper sash and vertically movable lower sash, a formed horizontal upperrail in said lower sash having a groove therein extending the Width ofsaid sash adjacent to an abutting horizontal rail of said upper sash,and a weather strip consisting of a binder and 4 woven pile fabricfirmly held in said binder insertedin said groove and extending beyondthe ends of said groove, said weather strip extensions conforming toexterior surfaces of said lower sash adjacent to said main frame.

4. In a window sash having upper and bottom horizontal rails andvertical rails joined to said horizontal rails at their respective ends,said sash being slidable in a supporting frame; a resilient Weatherstripping positioned on the side of the upper horizontal rail throughoutits length and extended around the end of said sash, closing the openingbetween said sash and the supporting frame.

5. In a window having a plurality of sash vertically slidable in asupporting frame, each of said sash having joined horizontal andvertical rails, the exterior side of said vertical rails adjacent tosaid frame having a channel contour accommodating a sash guide on saidframe; a resilient weather stripping positioned on the side of ahorizontal rail adjacent to a rail of an abutting sash, extending beyondthe ends of said horizontal rail in substantially U form, embracing saidcontour in each of the joining vertical rails and intimately contactingthe abutting frame.
